HoFo user awwong just dropped me a note that the OTA Jellybean update for the Nexus S was just pushed out.
Did you get yours yet?
I've updated my Nexus S (T-Mobile, Wind AWS variant) to Android 4.1.1 Jelly Bean a few hours ago and have been testing it. So far I like the taste of it! I connected to wifi to make the download faster.
At this stage, everyone should be backhauling sectors to their theoretical maxes in major urban cores like Manhattan anyway. In this case, a 150 Mbps measurement is to be expected on an empty sector....
